About These Birds
Tawny-breasted Tinamou
A medium-sized tinamou with plain tawny-brown upperparts and warm rufous-orange breast. Found in Andean forests of Ecuador, Colombia, and Peru. Secretive and terrestrial; known primarily from its loud mournful call heard at dawn. Forages in dense undergrowth for seeds and invertebrates.
Great Tinamou
The largest regularly occurring tinamou, with brownish-grey plumage, barred wings, and a pale belly. Common in lowland Neotropical rainforest from Mexico to Bolivia. Males incubate glossy teal-colored eggs. Their haunting multi-note calls resonate through the forest, making them acoustically conspicuous yet visually elusive.
